The problem with this is the fact that BIOS device addresses _change_
when you remove a drive.  So do you setup GRUB on the 2nd+ device to be
BIOS fixed disk 81h (the first device has failed, but has not been
removed) or BIOS fixed disk 80h (the first device has failed and has
been removed)?

Even though the Linux device name might not change, GRUB needs to know
what BIOS fixed disk assignment the disk is, and that _could_ change on
the 2nd+ redundant boot devices.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
